DAVID B. MARWICKOF NEW BRITAIN, CONNECTICUT, ASSIGNOR OF oNE- HALF TO ETHELBERT A. MOORE,

To all whom it'mwy concern:

Be it known that I, DAVID-B. MARWICK, a

citizen of the United Stateiresiding at New Britain, in'the county of Hartford and State of Connecticut, have invented certain new and-useful Improvements in Machines for Bundling Scrap, of which the following is a specification. This inventionrelates to means for form- 1ng scrap into rolls or" balls, and hasfor its objectthe provision of a machine by which the accumulated scrap may be-readily with drawn from the floor of amill and coiled and consolidated into a compact portable ball or bundle,

v ready for any subsequent procedure desired. 7

" A further object of the invention is the provision of a mandrel for windingthe scrap,

and in connection with said mandrel, a device cooperating therewith in the formation of said scrap into a consolidated mass, ready for transportation, or for admission into a reheatingor melting furnace.

A further ob ect of the invention isv theprovision of meanswhereby the device coopcrating with the mandrel'may be shifted to dislodge the compacted ball or mass from the Y mandrel.

' which the .vention. machine, Fig. 3 is a detail, partially in sec- A further object of the invention the provision, in connection withthe devicefor com acting and governing the formation of I the all ormass of scrap, of a taperedmandrel havin means for instance, a slot, in.

first strand of scrap may be inserted, the subsequent intermingled scrap being drawn forward by said first strand secured in any suitable way to said mandrel.

Other objects of the invention relate to de tails which will be hereinafter-described. In the accompanying drawings, Figure '1 is a plan view of a machine embodying myin' Fig. 2 is a front elevation of said tion, showing a ball of scrap in readiness to be discharged from the mandrel. Fig. 4 is .a

view, partially in sectionand in elevation,

illustrating the mode of feeding the scrap in the-formation of the ball, the section being taken-on line 44 of Fig. 3, looking in the di-.

rection of the arrow. Fig. 5 is .a longitudinal, horizontal section, taken on line 5-5 of Fig.2, and Fig. 6 is a transverse section taken on hne 6--6v of Fig. 5., looking in the direction of the arrow.

' Like 1 numerals designate similar throughout the several views.

Referring to the drawings, the numeral '1 designates a base provided with vertical posts or u rights 2, 3 and 4 in bearings of which the sha ts of themachine are journale'd.

Threaded upon this part 11 of the bearin' is a hub '12,- having a groove 13 to receive t e collar 5, and a remsaid flange the hub is of rectangular or-boxcylindrical tip 25 of the mandrel fias shown 'inFig. -5. e

To actuate these levers a conica 'sle'eve37 is fitted loosely on the driving-shaft, and said sleeve may be actuated by a; lever 38 pivoted at 39 to a bracket 40 projecting from the inner side of the-upright l. Any desired means may be employed, however, as substitutes for those shown and describedfor clutching 5 the pulleyto the-shaft Without departure from the invention. I

Beyond the pulley the shaft is provided at its' endwi'th a. pinion 41, in mesh-with the gear'8 of the mandrel-carrying shaft 5 Designated by 42 in'Fig. 4 is a mass of in. termingled scrap which is to be drawn from ,the floor or other support of the mill and to be wound upon the mandrel 6 into a roll or 'ball 43.

the operation of the invention the first strands of thisfscrap'are, in the construction shown ,d'eflected at the end as at 44, Fig. 4,

l set in operation. I As the mandrel revolves'it will draw in and and areinserted'in the slot 7 of the tapering mandrel 6,"and after this has been done the pulley'35 is clutched to the shaft 34 by means stitutes' for 'said means, and the machineis wind upon itself a mass of the interlaced and into a bundle'43. shown the sections 15 and 1 8 of'the yoke are shaped on their inner sides to a substantially elliptical contour, and these sections as the mass of scrap accumulates on the mandrel. determine the form of the bundle and compact the strands composingthe same so thata' solid mass of scrap ready for transportation is produced.- During the 1 winding and. compacting operation the'sleeve 2 6is shifted. to the position represented .in Fig; 5, and as said sleeve ,is of isquare or rectangular contour on its inner surface. it fits over the like surfaces of the hub 12 and bearin 2 and locks said hub against movement. I he the means shown are preferable for accomplishing this result it is distinctly to be understood that other means may be employed as substitutes therefor, without departure from the invention.

For connecting this pulley '-to the shaft a common form of friction-clutch may in' the manner described.

After the biindle has been formed it is rolled around'in the yoke by the mandrel,

and the outer surface thereof is polishedand the strands are compacted into a solid ball with no projecting-peripheral edges or surfaces ready for discharge from the. mandrel.

of the mandrel 6, releasing it therefrom; after which by detaching. the section 18 of the yoke thus push the ball along the inclined surface -m the manner above described, theball orf bundle may be readily removed from said mandrel.

To place the machine'in condition for a renewal of the operation, pulley 35 is released by the means shown, or by other means, and

is permitted. to run idly upon the drivingshaft, after which the yoke is grasped by 1 hand and the hub 12 thereof is runback upon the threaded section of the bearing, and locked in place thereon by shifting the sleeve 26 to theposition illustrated in said Fig. 5. Lhen-a new charge of scrap is to be added to the bundle in process of formation, all that it is necessary to do is to connect one or more of the strands with those of the coil or bundle, and to then set the machine in operation merely thro'wn intoa commin gled or inter laced mass upon the floor of the mill may be readily formed into a compact bundle, and
